Causes

This problem is caused by one of the following reasons:

• The MSI installer package is not in the Windows Installer cache at %WINDIR%\Installer.
• The Commvault instance key was manually removed and an installation of the earlier version of the instance is being attempted. For example, on a computer that has a Service Pack 10 installed, the Commvault instance key is manually removed and Service Pack 9 installation is attempted.

Resolution

Resolution 1

Use the Microsoft Program Install and Uninstall tool to uninstall the package.

For more information, see Fix problems that block programs from being installed or removed on the Microsoft Support website.

Resolution 2

1. Find the old MSI GUID in the MSI log file. For example, you can find the old MSI GUID {13A3A91C-6A69-4C89-9D43-ADBB63DEF4CD} from the following line in the log file:

Property(S): WIX_DOWNGRADE_DETECTED = {13A3A91C-6A69-4C89-9D43-ADBB63DEF4CD}\

2. In a command window, run the msiexec /x command and uninstall the MSI. For example, you can run msiexec /x {13A3A91C-6A69-4C89-9D43-ADBB63DEF4CD} in a cmd window to uninstall the MSI guid {13A3A91C-6A69-4C89-9D43-ADBB63DEF4CD}
